But first, a little background would be in order. You can learn more about how we ensure our content is accurate and current by reading our editorial policy. LabFinder allows you to search and select Self-Pay when booking a Lyme Disease Test. Given the prevalence and seeming elusiveness of the disease, some of the logical questions concerned persons would ask are: what is the most accurate test for Lyme disease And when should I get checked for Lyme disease This article will proffer answers to these and many other related questions. Healthline has strict sourcing guidelines and relies on peer-reviewed studies, academic research institutions, and medical associations. The BCA Assay is a simple and cost-effective test that gives straightforward positive or negative results. For example, the 41 and 66 and the 93 kDa bands are known as sites on the blots that can attract. Testing positive on one to three 'bands' on the IgG Western blot may not be significant at all. This lack of sensitivity could result in a person with Lyme disease testing negative. Since it can take several weeks or months before antibodies are found in blood, the Western blot test may not always be reliable. Antibody-based tests (ELISA, IFA, Western blot, Immunoblot). If it causes a change in color, antibodies to a specific infection have been detected. The proteins are placed onto blotting paper that’s made from a material such as nitrocellulose.Īn enzyme is added to the paper. The Western blot uses a procedure called gel electrophoresis to identify and separate proteins by molecular weight and length. While the western blot test isn’t 100 accurate, and even IGeneX insinuates this, their methods and techniques used for identifying Lyme antibodies are more modern and advanced than other labs. If you develop a viral, fungal, or bacterial infection, your healthy immune system will respond to the presence of foreign antigens by producing unique antibodies that bind to the antigen, triggering recruitment of inflammatory cells that fight the infection. IGeneX is considered the go-to laboratory by Lyme doctors and physicians for testing a patient for Lyme disease with the western blot test.
The Western blot test looks for the antibodies against an infection, not the infection itself. If you get a positive result for Lyme disease or HIV after taking an enzyme-linked immunosorbent assay (ELISA) test, your doctor may recommend a Western blot test to you. It was invented in 1979 to identify ribosomal RNA binding proteins. This test can also identify Lyme disease and will often be used to confirm the results of the ELISA test. The Western blot test is also known as a protein immunoblot test or immunoblotting. Average Cost (without insurance) Enzyme-linked immunosorbent assay (ELISA) This is the most common and sensitive test used to identify Lyme disease antibodies.
